#### Q11. pg_stat_statements をインストールしているのにレポートでプランの統計情報が出てきません。

pg_stat_statements が public 以外のスキーマにインストールされている可能性があります。
この場合はログを確認すると繰り返し以下の様なエラーが記録されているはずです。

ERROR: pg_statsinfo: query failed: ERROR: relation "pg_stat_statements" does not exist

この場合は一旦 DROP EXTENSION したのち、明示的にスキーマを public と指定して CREATE EXTENSION を実行しなおしてください。

CREATE EXTENSION pg_stat_statements SCHEMA public;

#### Q11. There's no plan statistics in a textual report although pg_stat_statements has been installed.

pg_stat_statements may be installed in the schema other than "public". You
will find the following lines in server log for the case.

ERROR: pg_statsinfo: query failed: ERROR: relation "pg_stat_statements" does not exist

Do DROP EXTENSION, then CREATE EXTENSION again explicitly specifying
public as installation schema in order to fix this.

CREATE EXTENSION pg_stat_statements SCHEMA public;
